+09:02 < wsa_> hi geert
+09:02 < wsa_> hi simon

+09:03 < morimoto> Hi
+09:03 < wsa_> hi morimoto-san
+09:03 < morimoto> shimoda-san will be here
+09:03 < morimoto> soon
+09:04 < wsa_> good
+09:04 -!- shimoda [~shimoda@relprex1.renesas.com] has joined #periperi-io
+09:04 < shimoda> hi
+09:04 < wsa_> hi shimoda-san
+09:04 < shimoda> I'm sorry for late
+09:05 < wsa_> no worries
+09:05 < wsa_> but let's get started
+09:05 < wsa_> any questions to the updates I did to the todo file? any further updates?
+09:06 <@horms> none from my side
+09:06  * geertu checks git
+09:07 < wsa_> horms: I will apply your ARCH_RENESAS patch for I2C today or tomorrow
+09:08 <@horms> thanks. I hope to roll out the remaining dozen or so patches for ARCH_RENESAS (not I2C!) soonish
+09:08 < geertu> I think the SCIF tasks should be postponed to v4.7.
+09:09 < geertu> For MSIOF, I tested the fix in the BSP, but it doesn't work for me.
+09:09 < geertu> Perhaps it only works for other SPI modes than mode 0?
+09:09 < geertu> The fix modifies some timing parameters. I have a deeper look with the logic analyzer to see if I can tune the parameters to make it work.
+09:09 < wsa_> geertu: ok, moved SCIF tasks to v4.7
+09:10 < geertu> For SPI slave, I noticed something interesting on the mailing list.
+09:11 < geertu> Apparently some devices have an SPI_READY pin, so the slave can indicate it's ready to provide data.
+09:11 < wsa_> geertu: so, it is mode0 that doesn't work? does it work on gen2?
+09:11 < geertu> msiof works on Koelsch with my test board (2 HC595 shift registers and LEDs)
+09:12 < geertu> Cfr. the pictures in thread "r8a7795 SYS-DMAC issues (was: Re: [PATCH] [RFC] arm64: renesas: r8a7795: Complete SYS-DMAC nodes)" on periperi-ml
+09:13 < geertu> I emailed the SPI_READY guy to ask for SPI slave hardware supporting this. He couldn't say more than it's "for automotive", and CCed our friend Dirk Behme.
+09:13 < geertu> So perhaps I have found the requestor of the feature ;-)
+09:14 < wsa_> :)
+09:15 < wsa_> Nice detective work ;)
+09:15 < geertu> I'll check with Dirk
+09:15 < wsa_> so, i'll leave the MSIOF issues for 4.6 and wish you good luck
+09:15 < geertu> Thx! ;-)
+09:16 < wsa_> shimoda-san: any news on the USB side?
+09:17 < shimoda> wsa_: today usb phy patch was merged to allow cpg driver of gen3
+09:17 < shimoda> so
+09:17 < shimoda> so, i would like to send some integration patches.
+09:18 < shimoda> however, for ehci ch 0 patch is "RFC", I will not send such patch.
+09:18 < shimoda> horms: is it acceptable for v4.6?
+09:18 <@horms> shimoda: if you are very quick
+09:19 <@horms> I'd like to finalise my branches tomorrow
+09:19 < shimoda> horms: i got it, i will try it today
+09:20 < wsa_> great
+09:20 < shimoda> and I have other topic from BSP team
+09:20 < shimoda> they would like to support DRIF module for gen3
+09:21 <@horms> shimoda: thanks
+09:21 < shimoda> and i got a datasheet of DRIF
+09:21 < geertu> DRIF used to be in older versions of the datasheet
+09:22 < shimoda> I heard REE/Phil is developing it
+09:22 < geertu> It's "just" 2x MSIOF slave, right?
+09:22 < geertu> Older R-CarH3_01_U12_DRIF_0010_e.doc says:
+09:22 < geertu> "This LSI includes two sets of DRIF (Digital Radio Interface). Each of DRIF is composed of two MSIOF modules, which supports Slave Receive Mode only."
+09:22 < geertu> But latest 0.5E datasheet has only some DRIF remainings (pfc/mstp/dmac)
+09:23 < shimoda> on gen3 manual of DRIF, "This LSI includes four sets of DRIF"
+09:25 < wsa_> Hmm, so is this basically the same as this task?
+09:25 < wsa_> "SPI,2016-05-31,plan,geert,Implement initial SPI slave prototype support for R-Car Gen2"
+09:25 < morimoto> geert: latest DRIF says
+09:25 < wsa_> we haven't specified which SPI-core to use for that, have we?
+09:25 < morimoto>  
+09:25 < morimoto> This LSI includes four sets of DRIF (Digital Radio Interface). Each of DRIF is composed by two sub modules. In this
+09:25 < morimoto> module, S3D2φ is used as module clock, clock input from LSI is used as serial clock for reception.
+09:25 < geertu> wsa_: MSIOF slave
+09:26 < geertu> Yeah, besides working MSIOF slave, another difficulty may be in tying the two instances together
+09:28 < geertu> Do we know what (dual SPI master) hardware is connected to DRIF?
+09:28 < geertu> Can we get test hardware?
+09:29 < wsa_> shimoda: so, the task looks to me to watch for Phil's DRIF patches and test them when they come along?
+09:29 < shimoda> geertu: i will ask someone
+09:30 < shimoda> wsa_: i think so if possible
+09:30 < wsa_> shimoda: was there a deadline mentioned?
+09:32 < shimoda> wsa_: i don't know, so I will ask bsp team
+09:32 < geertu> FWIW, SPI (MSIOF) slave has 2016-05-31
+09:32 < wsa_> geertu: I'm inclined to assign this task to you? ;)
+09:33 < geertu> Let's wait and see...
+09:34 < wsa_> OK, so I added this task:
+09:34 < wsa_> "DRIF,?,plan,?,Assist Phil in developing the driver"
+09:34 < shimoda> wsa_: this task is good to me
+09:35 < wsa_> morimoto: any news on the Gen3-Thermal driver?
+09:35 < wsa_> shimoda: good
+09:35 < morimoto> We will have meeting about that with RVC next month
+09:35 < morimoto> (I think I can create this driver before that :)
+09:36 < wsa_> :)
+09:36 < wsa_> so, the deadline "2016-03-31" is still valid?
+09:36 < morimoto> I think postpone is good for me
+09:38 < wsa_> 2016-06-31?
+09:38 < morimoto> good !
+09:38 < morimoto> And I think it will be RVC task
+09:39 < wsa_> khim-san?
+09:39 < morimoto> I think so
+09:39 < wsa_> I was about to ask about him anyway
+09:40 < wsa_> I assume you would ask on the periperi-list if khim-san needs additional tasks to be assigend?
+09:40 < wsa_> Or how is it handled?
+09:41 < morimoto> Umm
+09:41 < morimoto> I don't know. Do we need track his task in periperi-list ?
+09:43 < wsa_> Either him, or the person petting him :)
+09:43 < wsa_> we will see
+09:43 < wsa_> for now, I leave the thermal task to you, morimoto-san. OK?
+09:43 < morimoto> OK.
+09:43 < morimoto> I will report the result
+09:44 < wsa_> thanks
+09:46 < wsa_> shimoda, morimoto: can one of you ask about this strange bit in SDHI?
+09:47 < wsa_> this thread on periperi: "[periperi] Q: ACC_REG in Gen2 SDHI Docs?"
+09:47 < morimoto> OK, I can ask it to HW guys
+09:48 < wsa_> and is my knowledge accurate that the next Gen3-BSP release is end of February?
+09:48 < wsa_> morimoto: Thanks!
+09:48 <@horms> wsa_: i expect to get an update on that on Friday
+09:49 < wsa_> horms: urgent BSP release?
+09:50 <@horms> wsa_: there is a BSP meeting on friday. I expect the timing of the forthcoming releases to be discussed there.
+09:51 < wsa_> ah, okay
+09:51 < wsa_> horms: can you post the result for the next release on periperi?
+09:52 <@horms> sure
+09:52 < wsa_> thanks
+09:52 <@horms> be aware that there are internal and external releases
+09:53 <@horms> its the external ones that go in kernel.org, to customers, etc...
+09:53 < wsa_> i am interested in the next update I can have access to
+09:53 <@horms> understood
+09:53 <@horms> me too!
+09:53 < wsa_> :D
+09:54 < shimoda> wsa_: next Gen3 BSP release is end of March
+09:54 <@horms> I can see the internal ones, but its not so interesting afik
+09:54 < wsa_> end of march, okay thanks
+09:54 < wsa_> I ask because I couldn't get 8-bit eMMC to work
+09:55 < wsa_> it is planned for the next BSP, so I wanted to check if there is some gory detail i am missing
+09:55 < wsa_> shimoda-san kindly sent me some patches but the gory detail was not in there
+09:55 < wsa_> so I was interested in building the BSP and check if/how it works
+09:56 < wsa_> that's the full story
+09:56 < shimoda> wsa_: thanks for the full story
+09:57 < shimoda> I have internal patch set of the current internal bsp
+09:57 < wsa_> one more info from my side: i have now access to the Coverity-reports for the upstream kernel. I tried some patterns finding renesas-specific files and there were some hits.
+09:58 < wsa_> i'll investigate if they are not false positives and fix them along if there are not too many
+09:58 < wsa_> if there is a bunch, it may be worth to make a task out of it
+09:59 < wsa_> but we can discuss that later
+09:59 < wsa_> that's all from my side
+09:59 < wsa_> are we done?
+09:59 < geertu> I have another question
+10:00 < geertu> Anyone who knows what's the rationale behind the private review of the CANFD driver?
+10:00 <@horms> not i
+10:01 < morimoto> I don't know background, but Munakata-san and REE had meeting about it
+10:01 < morimoto> and it seems it was REE's challenge
+10:01 < morimoto> REE want to send it to ML
+10:01 < geertu> Good ;-)
+10:01 < morimoto> but they want private review as 1st step
+10:02 < morimoto> So, we need to tell him to send it to ML :)
+10:02 < wsa_> wearing my maintainer's hat, I appreciate if companies do the first rounds of review internally :)
+10:02 < morimoto> :)
+10:03 < wsa_> looks like we are done now
+10:03 < geertu> wsa_: And wearing your company-internal hat? ;-)
+10:04 < wsa_> geertu: that hat tells me it is benefitial to be nice to maintainers :D
+10:06 < wsa_> and, it looks more professional to have proper patches sent out
+10:06 < wsa_> and the first version really had some way to go
+10:06 < wsa_> OK, let's call it a day
+10:06 < wsa_> thank you guys!
+10:06 < morimoto> thanks
+10:07 < shimoda> thank you!
+10:07 < morimoto> wsa_: I would like to confirm
+10:07 < geertu> thx
+10:07 < geertu> bye
+10:07 < morimoto> bye
+10:07 < morimoto> wsa_: about your question about SDHI
+10:07 < wsa_> yes
+10:08 < morimoto> Are you checking sh_mobile_sdhi_sdbuf_width() ??
+10:08 < morimoto> I'm missing point
+10:09 < wsa_> yes, i mean this function
+10:09 < wsa_> for version 0x490c, it always uses 0x0001 for 32-bit
+10:10 < morimoto> yes
+10:10 < wsa_> now, this document for channels 0+1
+10:10 < wsa_>  R8A7790(R-CarH2) SD Host Interface CH0,CH1 Hardware Manual(V00R01E).pdf
+10:10 < wsa_> chapter 1.2.23
+10:11 < morimoto> verion = 0x490c = CH2,3
+10:11 < wsa_> 0: 32-bit access
+10:11 < wsa_> and in 1.2.22
+10:11 < morimoto> for CH0,1 ?
+10:11 < wsa_> 16’h490C
+10:12 < morimoto> ?
+10:12 < wsa_> the filename of the document says channel 0+1, yes
+10:12 < wsa_> shall i send you the document I am referring to?
+10:13 < wsa_> (i got this from the renesas-ftp once)
+10:13 < morimoto> please wait
+10:14 < morimoto> ver = 0x490c = CH2,3 = 0: 16bit, 1:32bit
+10:14 < morimoto> ver = 0xCB0D = CH0,1 = 0: 32bit, 1:16bit
+10:15 < morimoto> Is this correct for you?
+10:16 < wsa_> that would be nice
+10:16 < wsa_> so, the document i have has an error?
+10:17 < morimoto> does you document is not same as above ?
+10:17 < wsa_> because it says in 1.2.22 initial value is "16’h490C"
+10:17 < morimoto> if so, your document was wrong version 
+10:18 < morimoto> I ping-pong:ed this with SDHI guys before
+10:18 < morimoto> (I forgot detail...)
+10:18 < wsa_> can i have access to the latest version?
+10:18 < morimoto> What is your document version ?
+10:18 < morimoto> I have is
+10:19 < morimoto> CH2,3 = V00R03E
+10:19 < wsa_> i have this
+10:19 < wsa_> R8A7790(R-CarH2) SD Host Interface CH0,CH1 Hardware Manual(V00R01E).pdf
+10:19 < morimoto> CH0,1 = V00R05E
+10:19 < morimoto> oops, too old :)
+10:19 < wsa_> and R8A7790(R-CarH2) SD Host Interface CH2,CH3 Hardware Manual(V00R01E).pdf
+10:20 < wsa_> yes, looks like it :)
+10:20 < morimoto> OK, we now find the bug :)
+10:20 < morimoto> I wounder how did you get it ?
+10:20 < morimoto> Ah, from FTP
+10:20 < wsa_> i was SO hoping for a documentation error :)
+10:21 <@horms> I think I'll depart now unless there is anything more (non SDHI) to discuss
+10:21 < morimoto> Oops, sorry Simon
+10:22 < morimoto> Yes, IO meeting was finished I think
+10:22 <@horms> No problem
+10:22 -!- horms [~horms@reginn.isobedori.kobe.vergenet.net] has left #periperi-io ["Leaving"]
+10:22 < morimoto> OK, I will ask to Jinso to send latest SDHI version to you
+10:22 < wsa_> thanks!
+10:22 < morimoto> was_: do you think your issue will be solved by it ?
+10:22 < morimoto> s/was_/wsa_/
+10:23 < wsa_> yes, I will add comments to the upstream driver to make things clear
+10:23 < wsa_> luckily, no code changes are needed
+10:23 < morimoto> I hope so :)
+10:23 < morimoto> Thank you for your hard work
+10:24 < morimoto> I will ask it tomorrow. (because of time-zone issue :)
+10:24 < wsa_> very welcome
+10:24 < morimoto> OK, thanks. bye
+10:24 < wsa_> thanks for all your assistance
+10:24 < wsa_> tommorow is fine, cya!
